A15i Wide/Focus line source element

A single A15i Wide/Focus can be used as a line source element. In this conguration, the system operates over the
nominal bandwidth of the enclosure.
The [A15_FI] preset delivers a reference frequency response in short throw applications.
The A15i Wide/Focus enclosures are driven by the LA2Xi / LA4X / LA8 / LA12X amplied controllers.

With a complementary subwoofer, the system is extended in the low end and the LF contour is reinforced.
The [A15_FI] preset delivers a reference frequency response in short throw applications. The [KS21_60] preset provides
KS21i with an upper frequency limit at 60 Hz.
The A15i Wide/Focus and KS21i enclosures are driven by the LA2Xi / LA4X / LA8 / LA12X amplied controllers.
